The purpose of these studies was to assess the validity of self-reported stress-related growth (SRG). In Study 1, individuals with breast cancer (n = 70) generally did not report greater well-being than a matched comparison group (n = 70). In Study 2, there were no significant differences in well-being between undergraduate students who said that something positive had come out of their worst stressor (n = 34) and those who reported no positives (n = 34). In Study 3, specific domains of SRG assessed in undergraduate students (n = 96) generally were not uniquely related to corresponding well-being measures. Thus, the authors found fairly little evidence for the validity of self-reported SRG. Future research directions are highlighted.
